A kind of the phthalate ester that phthalate diethyl (フタル diethyl British: Diethyl phthalate, abbreviated designation DEP) is expressed in chemical formula C12H14O4.
Use
The main use is used in a synthetic resin plasticizer as a solvent and a reservation agent of the fragrance. The annual amount of production in Japan from 1996 through 2001 changes at approximately 700 tons [3].
Safe
The toxicity is at the same level as ethylene glycol and is smaller than the dimethyl phthalate. In the case of oral administration, the LD-50 (LD50) by the animal experiment was all 1,000 mg/kg in 6,172 mg/kg, the rabbits with 8,600 mg/kg, a mouse in a rat marmot [3]. Exercise of dermatitis and sperm inhibition is seen for the Homo sapiens, but the carcinogenicity is not confirmed [3]. I produce a poisonous gas by combustion [4]. I correspond to the fourth kind dangerous materials third oil to fix for the Fire Services Act [5].
